Thermal Extractor Balls
Thermal Extractor Balls are small thermal media spheres offered in multiple materials and two sizes (2.5mm and 3.0mm). This single product page can be set up with variants so shoppers choose the material and size they want from one listing.
Each variant is listed as “enough to fill one Tempest Cap and some extra,” with approximate piece counts per size. Material properties (density, thermal conductivity, and cap filling weight) are provided below for accurate comparison.
FAQs
- What is this product? A set of small thermal media balls sold by material and size as variants on one product page.
- What sizes are available? 2.5mm and 3.0mm (select your size in the variant picker).
- How many pieces do I get? Approximately 100 pieces for 2.5mm and approximately 50 pieces for 3.0mm (actual count may vary by packing).
- Do all variants include the same amount? Each listing states it’s enough to fill one Tempest Cap and some extra, but the total weight differs by material.
- Are these sold as a mixed set? No—each variant corresponds to one selected material and one selected size.
- Is this intended for minors? The source product pages include an 18+ warning; keep out of reach of children and pets.
